Thee Beginnings of Navigation: Reading thee Sky andSea

Humanity 's desire to explore beyond familiar horizons spurred thee arliest experiments in vigation. Long before compasses or GPS, our antropoors looked te heavens ante thee natural experts for guidance.

Thee Compass: Magnetyk Revolution

Perhaps thee single most important innovation in vigation was te magnetic compas. Originating in Chin during thee Han Dynasty (around 200 BC), thee compas initially was used for geomancy and divination rather than travel.
